(54)	Blood-pressure measuring apparatus having augmentation-index determining function

(57) A blood-pressure measuring apparatus (10) comprising a cuff (12) which is adapted to be worn on a portion (14) of a living subject to press the portion; an augmentation-index determining means (66) for determining an augmentation index of the subject based on a cuff pulse wave obtained from the cuff; and a cuff-pulse-wave obtaining means (53) for obtaining, during a pressing period in which the cuff presses the portion of the subject for measuring a blood pressure of the subject, the cuff pulse wave from the cuff so that the augmentation-index determining means determines the augmentation index based on the obtained cuff pulse wave.
